DORIG ELECTRONIC TIMEPROGRAMMER 2 Sheets-Sheet 2 Filed Nov. 5, 1963 IN VENTOR United StatesPatent 3,246,463 ELECTRONIC TIME PROGRAMMER Jean J. Dorig, 1815 WalnutSt., Lafleche, Quebec, Canada Filed Nov. 5, 1963, Ser. No. 321,633 11Claims. (Cl. 58-150) This invention relates generally to improvements inautomatic signals and appointment reminder devices, and moreparticularly to an electronic time programmer that provides both audibleand visual signals automatically operable at predetermined periods oftime, the periods at which the signals become activated beingselectively predetermined and their duration being controlled manually.

It is conventional practice for people engaged in various business andprofessional occupations to utilize some form of device to remind themof specific duties which need to be performed within or upon a giventime, appointments which have to be kept during their working day andimportant activities, the commission of which is invariably related toand governed by the time of day.

The usual reminder device generally consists of a desk calendar havingthe typical loose leaf tear off or flip over sheet, each sheet servingfor one particular day within the year and normally having ruledsubdivisions imprinted thereon related to hourly or half hourly periodsof the particular day. Therefore, an executive or his secretary wishingto be reminded of an appointment to be held say, for instance, attwo-thirty pm. on a given date, would enter brief particulars at therelative time period marked on the calendar.

' While this method serves as a reminder device of some value, itslimitations are immediately apparent. Once an entry has been made, theperson involved still relies almost solely onhis memory, having to referconstantly to the calendar, particularly if, as is usually the case,there is a multiplicity of appointments, duties and imperatives to becomplied with during the day. Thus, an executive working on a tightschedule or a secretary having numerous duties to perform may, althoughsome time previously having entered an appointment on the calendar,forget that such an appointment was even made, the pressure of workoften being such as to divert the attention for periods of time muchlonger than originally anticipated.

In order to overcome the limited value of the conventional-desk calendaras a reminder device, numerous alternatives have been proposed suchalternatives generally involving electrical, mechanical orelectro-mechanical units adapted to issue some form of Warning orreminder either visual or audible at a given time period during theworking day.

While such devices as have heretofore been proposed appear to fulfilltheir various purposes they yet suffer from certain inherentdisadvantages, not least among them being their complexity ofconstruction and consequently the relatively highcost of manufacturethereof.

Having in mind therefore, the utility of an appointment warning deviceof thenature heretofore described and realizing the value of such anappliance in commerce, in dustry and other fields of activity, it is aprime object of this invention to provide an electronic time programmerembodying means therein whereby a reliable reminder of appointments tobe kept and duties to be performed is readily available.

. It is another important object of the present invention to provide anelectronic time programmer which utilizes a, conventional electric clockand a standard yearly desk calendar of the type having a plurality ofindividual tear off sheets, each sheet having indicia imprinted thereonrelative to time periods of the working day,

; Itis another object of this invention to provide an electronic timeprogrammer in which the electric clock is adapted to drive a travellingspring loaded roller contact, the contact being mounted upon andoperable along a pair of guide rails located immediately subjacent theleft marginal hourly marks on a daily calendar sheet, the said sheetacting as an insulator between the spring loaded roller contacts, theinvention particularly comprising a punch system adapted to punch aplurality of slots along the margin of the date sheets therebypermitting the roller contacts to touch each other therethrough, suchengagement being adapted to. create an. alarm or other signal such as,for instance, a visual signal or an audible signal, such meansindicating in a positive manner that an appointment is at hand or that aspecific function has to be performed.

Still another object of the instant invention resides in the provisionof an electronic time programmer the user of which may enter a note orwritten statement on the lines adjacent the time period markings of theindividual date page, thereafter forming a cut-out slot within the paperat that particular location in order to ensure that contact is madebetween the spring loaded roller contacts to create the warning signal.

Yet a further object of the invention seeks to provide an electronictime programmer the warning means of which, namely a light and a buzzer,may be terminated manually, either singly or together.

A still further object of this invention resides in the provision of anelectronic time programmer which, through the medium of a conventionalbell transformer, may be operated by normal mains supply.

Still another object of the instant invention resides in the provisionof an electronic time programmer of the character herein described whichdoes not require re-setting at the commencement of each individualworking day, the user thereof merely having to insert a fresh date sheetand slot the same as heretofore described.

Another object of the invention is to provide an electronic timeprogrammer which, while embodying the above advantages and objects isyet constructed from a minimum of component parts thereby allowing ofrelatively inexpensive manufacture.

The aforementioned and various other pertinent objects and features ofthe instant inventionwill become more readily apparent from thefollowing detailed description of parts and assemblies when taken inconjunction with the accompanying drawing in which like characters ofreference designate like parts in the several views and wherein:

FIG. 7 is a detailed side view of the slot puncher embodied in theinvention.

FIG. 8 is a schematic diagram of the electrical circuit embodied in theinvention.

Referring to FIGS. 1, 4 and 8 an electric time programmer generallydesignated by the arrow 11 includes a baseplate 12 of substantiallyrectangular configuration and having a circular cut-out section 13formed therein. Baseplate 12 also has formed on one side thereof aninverted V cut-out section 14.

Baseplate 12 has, mounted on one half of its area a compartmentconsisting of a storage deck 12a and a date sheet line up and supportassembly 15. Storage deck 12a is adapted to receive therein aconventional yearly calendar block 16, block 16 having a plurality ofindividual date pages each of the said pages having subdivisions of anormal working day located down the left hand margin thereof.

Mounted upon the upper edges of storage deck 12a is a rectangular, topdesk plate 17, plate 17 being adapted to support a date sheet thereonand to enable notation to be performed upon the said date sheet. Aninverted V cut-out section 17a, coplanar with cut-out section 14 inbaseplate 12 aids in the removal or insertion of calendar block 16 asmay be required.

An L shaped guide plate 18, afiixed to the right hand side of desk plate17, is adapted to line up each individual date page as it is torn offblock 16 and imposed on desk plate 17.

Mounted on the remaining section of baseplate 12 is a conventional belltransformer 19, transformer 19 having an output of approximately 16volts from a commercial A.C. mains input of 110 volts and supplyingpower to operate a conventional electrical clock 20 and signalling meanscomprising a warning lamp, and buzzer which form part of the assembly.Mounted centrally on baseplate 12 is electric clock 20, clock 20 runningdirectly off the 110 volts supply and being in circuit at all times. Twoelectric magnets 21 and 22 used to operate the warning lamp 23 andbuzzer 24 respectively are fitted to a support plate 25, plate 25 beingmounted on the lower left hand side of baseplate 12 with lamp 23 fittedinto a lamp holder 26. Lamp holder 26 is located just aft of buzzer 24which is mounted on a plate 27, plate 27 being afiixed to baseplate 12immediately behind support plate 25, the circuit being completed througha buzzer contact bracket 28. It should be noted that electro-magnets 21and 22 are of the mechanical self locking type when energized by meansof retainer plates 29 and 30, contact springs 31 and their cooperablelocking notches that form part of support plate 25.

Electro-magnets 21 and 22 may only be released manually, this beingaccomplished by depressing transparent push button switch plates 35 and36 respectively, the said switch plates being mounted on hinge springs37 and 38, springs 37 and 38 returning switch plates 35 and 36 to theirnormal position against inside of lever 61. Referring now to FIG. 3,electric clock 20 has embodied therein a main drive assembly 39,assembly 39 including a circular gear wheel 40 mounted concentricallyabout the hour finger mechanism of the clock. An endless chain 41disposed in a three sided configuration by means of two idler-pulleys 42and 43 is driven by the teeth 44 of chain 41 and is adapted to performone complete revolution every twenty-four hours. A first dog 45 isafiixed to chain 41 and projects outwardly therefrom, being adapted toengage with a projection 46a on contact drive assembly 46, dog 45 onchain 41 propelling assembly 46 downwardly as indicated by arrow Aduring the normal eight hour working day, say for example from 9 am. topm. Upon chain 41 having moved for a third of its total revolution, dog45 will automatically disengage with assembly 46, whereafter due to areturn mechanism detailed later on in this specification it returns tothe top position again as indicated by arrow B, there to remain untildog 45 on chain 41 engages again sixteen hours later.

' Referring now to FIGS. 1, 3, 5 and 6, contact drive.

4 48 and 49, rods 48 and 49 being mounted on a carriage base 50 atfixedto baseplate 12. Assembly 46 comprises a pair of roller contacts 51biased together by means of a helical spring 52, and mounted on a Uframe 53, U frame 53 being slidably operable along rods 48 and 49.

During operation roller contacts 51 are separated by and ride on eachside of the left hand marginal section edge of a date page, the circuitsto the two operating signals being completed by the contacting of rollercontacts 51 through pre-formed slots in the margin of the date page.Assembly 46 has included therein, an electro-magnet 54 mounted on anouter U frame 55, U frames 53 and 55 having a limited freedom ofmovement therebetween. Electro-magnet 54 is adapted to be energized inseries with the signal operating circuits and, upon becoming energized,attracts one end of U frame 53 within contact drive assembly 46, theaforementioned limited freedom allowing U frame 53 to move downwardly asmall distance thereby causing roller contacts 51 to move past the slotformed through the calendar page thereby becoming insulated from eachother.

Therefore, the circuits through all three electro-magnets are completedwhen contacts 51 are touching the cut-out slots, thereafter being almostimmediately broken upon the said contacts being propelled downwardly andonto the paper. However, due to the self-locking features of theelectro-magnets 21 and 22, the electric circuits to the warning lamp 23and warning buzzer 24 remain completed until broken by the manualdepression of push button switch plates 35 and 36.

Referring now to FIGS. 2, 5 and 7, in order to provide the punched outslots adjacent to the particular time when the warning signals arerequired to operate, a punch assembly 56 including a punch 57 and matrix58 is slidably located on rods 48 and 49 and may be adapted to punch outslots S at any position below the contact drive assembly 46, up to halfan hour or even closer to the time position of contacts 51.

A hingeable paper clamp 58, adapted to be located over carriage base 50,covers the complete traverse of contact drive assembly 46, and iscapable of being hingeably lifted during which operation an inwardlyformed section 58a engages with an extension piece 51a attached to thatsection bearing the uppermost of rollers 51 thereby separating rollercontacts 51 and allowing the date page to be inserted therebetween.Clamp 58 has a plurality of locating pins 59 formed at each end thereofand adapted to engage with cooperable holes 60 formed in desk plate 17,thereby passing through the date page at its upper end lower left handcorners and holding it firmly in position whereafter the slot S may bepunched and the appointments or schedules written in at the appropriatelocations.

Referring again to FIGS. 3 and 6, it will be seen that the returnmechanism for contact drive assembly 46 comprises a first guide pulley80, a second guide pulley 81, a

third guide pulley 82 and a storage pulley 83. A belt 84, having areserve length coiled within storage pulley 83 passes therefrom overpulley 81 to pulley 82 and thence to pulley 80, passing thereover to besecured at its end 84a to a retainer plate 85, retainer plate 85 beingaflixed to drive assembly 46 and movable therewith.

Belt 84 has attached thereto a driving dog 86, dog 86 being adjacentpulley 81 when drive assembly 46 is in the uppermost location.

Chain 41 has aflixed thereto a drive dog 45 as heretofore described, dog45 being located adjacent pulley 42 when assembly 46 is in theaforementioned uppermost position. Thus, upon dog 45 having engaged withprojection 46a and moved assembly 46 downwardly on the first eight hourleg of the cycle, dog 45 will disengage from projection 46a, travelingthereafter around pulley 43 and onto the second eight hour leg of thecycle. However, as assembly 46 moves downwardly, belt 84 is drawn overits respective guide pulleys 80, 82 and 81 thereby up to its topposition and completing the third eight.

hour leg of the cycle.

Storage pulley 83 has a spring loaded axle to which the end of theaforesaid reserve length of belt 84 is affixed, the Spring loaded axletaking up the slack in belt 84 as dog 86 is moved back towards pulley81.

Therefore, assembly 46 may be set to commence its operation at say,forinstance 9:00 am. traveling on the first eight hour downward leg toits bottom position at which location the time will be :00 pm, remainingthereat for the second eight hour leg at completion of which the timewill be 1:00 am, thereafter being moved upwardly through the third eighthour leg to its top po: sition at which the time will be 9:00 am.

.It will be readily understood that these time cycles are described asbeing typical of a normal eight hour operational day from 9:00 am. to5:00 pm.

A cover assembly 61 is detachably attached by con: ventional means tothe clock and drive section of baseplate 12 and is adapted to shieldtransformer 19, clock. 20, electro-magnets 21 and 22, warning lamp 23and buzzer 24,

Located substantially centrally of said cover assembly 61 is a circularglass 62 for viewing the clock face. Two rectangular cut-out sections 63and 64 are located directly over push button switch plates 35 and 36respectively allowing access thereto for the purpose of breaking thecircuits to warning lamp 23 and warning buzzer 24.

Power to the operation of electronic time programmer 11 is fed from a110 volt A.C. commercial mains supply via a conventional connector andelectrical lead. Clock 20 is in circuit at all times, but power to theprimary winding of bell transformer 19 (the secondary winding of whichsupplies a low voltage for operation of electro magnets 21, 22 and 54)the warning lamp 23 and buzzer 24 may be interrupted if desired by meansof a conventional single hole toggle switch 65 (shown in FIG. 4) mountedin any convenient location upon the device.

The general design of the individual parts of the invention as explainedabove may be varied according to requirements in regards to manufactureand production thereof, while still remaining within the spirit andprinciple of the invention, without prejudicing the novelty thereof.
